Portainer

In Portainer the site is a stack: a Docker Compose file you paste into Portainer.

On the host, create the data folder for the user the site runs as:

sudo mkdir -p /opt/3mf-library/data && sudo chown 1000:1000 /opt/3mf-library/data

Portainer → Stacks → Add stack. Name: 3mf-library. Build method: Web editor. Paste:

services:
  3mf-library:
    image: ghcr.io/jurjen74/3mf-library:${IMAGE_TAG:-latest}
    container_name: 3mf-library
    user: "${PUID:-1000}:${PGID:-1000}"
    ports:
      - "${PORT:-8085}:8080"
    environment:
      TZ: ${TZ:-UTC}
      TRUSTED_NETWORKS: ${TRUSTED_NETWORKS:-}
      KNOWN_PROXIES: ${KNOWN_PROXIES:-}
    volumes:
      - ${LIBRARY_DIR}:/library:ro
      - /opt/3mf-library/data:/data
    restart: unless-stopped
    mem_limit: ${MEMORY_LIMIT:-3g}
    security_opt:
      - no-new-privileges:true
    cap_drop:
      - ALL
    read_only: true
    tmpfs:
      - /tmp

Environment variables (below the editor, Add an environment variable):

Name	Value
`LIBRARY_DIR`	`/srv/3d-prints` (your models folder on the host)
`TRUSTED_NETWORKS`	`192.168.1.0/24`
`TZ`	`Europe/Amsterdam`
`PUID` / `PGID`	only if the models belong to another user than 1000

Deploy the stack. The container’s logs show Scan finished … files in … folders when it’s ready.
Open http://<host>:8085 and create the first account.

Add the NFS volume to the stack instead of LIBRARY_DIR:

services:
  3mf-library:
    volumes:
      - library:/library:ro
      - /opt/3mf-library/data:/data

volumes:
  library:
    driver: local
    driver_opts:
      type: nfs
      o: "addr=192.168.1.10,nfsvers=4.1,ro,soft,timeo=100"
      device: ":/volume1/3d-models"
